Title: Sensor diagnostic system
Inventor: KATO MASASHI
IPC: G01R31/00
Filed: 1988-09-19
Abstract: PURPOSE:To accurately grasp a cleaning cycle corresponding to the contamination of a sensor, in checking a margin by lowering the emitting quantity of light from a usual level, by setting said emitting quantity to a light emitting level different at every light emitting element. CONSTITUTION:In a sensor A, a light emitting element 3 is allowed to emit light at a light emitting level 10 by a light emitting quantity variable circuit 1 and a light emitting circuit 2 at the time of general use and, when a paper sheet blocks an optical axis, a light detection circuit 5 outputs a binarization level showing the presence of the paper sheet and, when the paper sheet does not block the optical axis, said circuit 5 outputs a binarization level showing the absence of the paper sheet. Next, at the time of the diagnosis of the sensor, the light emitting element 3 is allowed to light at a light emitting level 9. At this time, in such a case that the light detection circuit 5 detects the presence of the paper sheet in spite of the absence of the paper sheet, erroneous detection due to the adhesion of dust is judged to generate an alarm from a maintenance data memory and output circuit 6. In a sensor B, at the time of the diagnosis of the sensor, the light emitting element 3 is allowed to emit light at a light emitting level 7 to perform diagnosis. A maintenance person performing periodic inspection cleans only a sensor emitting an alarm to replace the same.

Title: Centralized karaoke control system
Inventor: TOMIZAWA AKIMORI
IPC: H04Q9/00
Filed: 1994-09-01
Abstract: PURPOSE: To surely execute supply of KARAOKE music data with respect to a selected music within a delay time allowed for the customer service by improving a net data transmission efficiency. CONSTITUTION: Plural terminals TE1-TEN consist of 1st terminals not having KARAOKE music data and 2nd terminals having KARAOKE music data. The both terminals have a function to receive KARAOKE music data from a center equipment C and other terminals together with a channel selection function. In the music selection by the 2nd terminals equipments, when KARAOKE music data are provided in its own terminal, no request of the data is made to the center equipment and other terminal but the data are transferred in its own terminal. As a result, a net data transmission efficiency is increased twice or more.

Title: Method and apparatus for adjusting inclination of ultrasonic inspection apparatus
Inventor: TAKISHITA YOSHIHIKO
IPC: G01N29/24
Filed: 1990-09-05
Abstract: PURPOSE:To enable correction of inclination of an array vibrator surface and reflection surface by a method wherein a reference vibrator and one each of other vibrators are excited in a pair and echo waves of the both are added up to observe a waveform obtained by plotting peak values of addition waveforms. CONSTITUTION:A vibrator A1 is selected as reference among array vibrators A1-A64 arranged in one direction. Then, the vibrators A1 and A2 are excited simultaneously. An ultrasonic reflection surface 3 is irradiated with an ultrasonic wave from the vibrators A1 and A2 and received waves of the reflected waves thereof are added up by an addition means to determine a peak value of a waveform. Subsequently, the same operation is performed from the pair of the vibrators A1 and A3 to the pair of those A1 and A64 to determine 63 peak values in total. A size of a relative inclination (angle theta) of an array vibration surface and an ultrasonic reflection surface is judged based on a change in frequency of a plot waveform obtained by plotting the peak values. When alteration is made so as to reduce the angle theta less and less, the plot waveform is turned to a waveform having neither maximal nor minimal point. At this point, a difference in water-based distance between the vibrator A1 and the vibrator A64 is below lambda/4 (represents wavelength of ultrasonic wave in water).

Title: Thin-film magnetic head
Inventor: YOSHIDA MAKOTO
IPC: G11B5/31
Filed: 1989-09-08
Abstract: PURPOSE:To suppress wiggle and to prevent the demagnetization of recording and the cracking of a protective film by setting the distance from the boundary point between the yoke region of an upper magnetic film and the rising part of a pole region to an air bearing surface in a specific range. CONSTITUTION:The distance D from a displacement point Y which is the boundary between the yoke region 42 of the upper magnetic film 4 and the rising part of the pole region 41 up to the air bearing surface 103 is set in the 2mum<D<12mum. The wiggle is smaller as the distance D becomes smaller at this time. The wiggle decreases to <=2.4% permissible service value in the range smaller than 12mum. Problems, such as the degradation in frequency characteristics by the easy tendency of the supersaturation of the pole in the gap region and the easy tendency of the protective film 9 to cracking, arise if the distance D decreases to <=2mum. The wiggle is suppressed in this way; in addition, the demagnetization of recording and the cracking of the protective film 9 are prevented.
